The Quantum Edge steel support in mattresses features a unique construction with narrow-diameter thicker gauge wire Quantum coils at the sides, head, and foot. This design enhances edge support, offering a firmer and more supportive edge than traditional mattresses. The Quantum Edge system replaces foam encasement, providing a sturdy seating edge and expanding the usable sleep surface. The Quantum steel narrow coils that provide the edge support allow the mattress to be a little more flexible compared to foam encased edge support when using on an adjustable base. Additionally, its design promotes 28% more airflow and breathability when comparing to a foam encased edge support, contributing to a comfortable sleep experience.

In mattresses, the optimal coil count for support has evolved. While older mattresses often had around 416 coils, modern mattress designs average around 768 coils for a queen-sized mattress. This increase in coil count enhances support and comfort, conforming more effectively to your body and promoting spinal alignment. However, it's not just about quantity; the type of coil and overall mattress design are crucial too. Higher coil counts can offer more support, especially in combination with modern mattress technologies. Do keep in mind more coils doesn't always mean better and can lead to increased pressure points so it's best to find the mattress that contours perfectly to your body and doesn't allow your body to sag or hammick in the mattress.

ThermaGel Memory Foam is an advanced type of memory foam infused with ThermaGel particles, engineered to provide both comfort and support. This material adapts to the unique body shape of the sleeper, offering superior support for joints and pressure points. The key feature of ThermaGel Memory Foam is its ability to regulate temperature. The infused ThermaGel particles work effectively to disperse heat away from the body, maintaining a cool and comfortable sleeping surface throughout the night. This makes ThermaGel Memory Foam especially beneficial for those who tend to sleep hot or live in warmer climates. The breathable nature of the foam, combined with the cooling properties of ThermaGel, enhances the overall sleep experience by ensuring a balanced temperature. Additionally, the adaptability of the foam contributes to relieving pressure and supporting the body efficiently, thereby extending the life of the mattress.

PCM, or Phase Change Material, in a mattress is an innovative technology designed for temperature regulation, enhancing sleep comfort. These materials change their state (solid, liquid, or vapor) in response to temperature variations. In the context of mattresses, PCMs typically shift from solid to liquid as they absorb heat, creating a cooling effect. This process also works in reverse, where they release heat as they solidify, thus warming up the mattress if it gets too cold. This bidirectional thermoregulation helps maintain an optimal sleeping temperature by redistributing body heat from warmer areas to cooler ones. PCMs are often incorporated into mattress covers or infused into the foam layers, especially in memory foam mattresses, to mitigate heat retention, a common issue with this mattress type. This technology not only enhances sleep quality by maintaining a comfortable temperature but also contributes to the durability and performance of the mattress.
